What purpose of Pattern$ in DeleteDirectory()?

[sec]

hi

DeleteDirectory()

Syntax

Result = DeleteDirectory(Directory$, Pattern$ [, Mode])

Pattern$ A pattern for deleting files within the directory. For example: "*.*" will delete any files in the directory. "*.exe" will delete only the .exe files. By default, a null Pattern$ ("") will delete all the files.

follow the help, two commands are different?
DeleteDirectory("C:\test\","*.bat",#PB_FileSystem_Force)
DeleteDirectory("C:\test\","",#PB_FileSystem_Force)

but they delete "test" dir in both case, so what purpose of Pattern$ in DeleteDirectory()?

thanks

If the directory is empty after deleting the matching files, then the directory also gets deleted (as expected).

Add another file in there that doesn't match the pattern, and only the pattern-matched files will be deleted.

any trick to delete all files w/o delete dir?

Maybe

Code: Select all

path$ = "c:\deletetest"
pattern$ = "*.*"
result = DeleteDirectory(path$,pattern$)
If result <> 0
  CreateDirectory(path$)
EndIf

any trick to delete all files w/o delete dir?

Code: Select all

DeleteDirectory("C:\test\","",#PB_FileSystem_Force|#PB_FileSystem_Recursive)
CreateDirectory("C:\test\")

That's how I've done it for years.
